Supplement Writing Services — Recover Every Dollar the Carrier Owes

Supplement writing is a skill — and most contractors don't have time to develop it. Our supplement writing services pair every claim with a former-adjuster writer who knows how carriers review, what documentation they require, and exactly how to make your supplement impossible to deny.

What This Service Covers

Former-Adjuster Writers

Our supplement writers worked inside insurance carriers before joining our team. They know the internal review process, the approval criteria, and the exact language that moves supplements through faster.

Xactimate Line Item Research

We research every applicable Xactimate code for your trade and damage type, then cross-check against the carrier's estimate to identify every missing or mispriced item.

Narrative & Justification Writing

Beyond the numbers, we write compelling narrative scope notes explaining why each item is necessary. Good narrative transforms a disputed item into an approved one.

Revision Cycles Included

If the carrier denies a supplement item and requests additional documentation, we revise and resubmit at no extra charge. We stay in the fight until your claim is resolved.

Xactimate Line Items We Recover
